Z Claims. 1

The present invention relates to a ball cock va1ve,particularly of the type used in-connection with toilet flushing tanks or the like.

The present invention is directed primarily to the. provision of a ball cock valve'of the character described which will not siphon any of the Water from the ilush tank back into the water line at the conclusion of the flushing and will also be noiseless in its operation, eliminating the hissing sound that generally accompanies the iiushing operation.

. The present inventionl is alsov directed to the provision of improved'floatand lever means for the operation of theballl cockvalve which is easily andaccurately adjustable for limiting the volume of water expendedrin the flushing operation.

Iv am Well. aware that antisiphon and antinoise ball cockvalves of the character towhich the present invention relates; have heretofore been made. However, Ias far' as I havebeen able to ascertain, such ball cock valves of theprior art have operated on the Water pressure principle,` depending for their anti-noise and antisiphon function upon the waterpressure or vacnum created Vin the `systeml'to operate anvairvadmitting valve to either open or close itlagainst gravity as the case may be. Such ball cock valves of the prior art have, therefore, been indirect in their yanti-noise and anti-Siphon action and more or less gradual in their operation so that they were incompletely effective inoperation, and not always'reliable in action. They could also easily jam. and 7become inoperative, independently of the `Water circulation through the valve.

It is the object of the present invention to provide a ball cockvalve of the character described in which the noise eliminating and the siphon preventing meansisdir'ectly and positively effected simultaneously with` theoperation of the Water admitting valve by the"v variation in Water level in the ush tank and'by the same'mechanical means, to thereby insure the'positive and effective operation ofi suchnoise' andsiplion" preventing whenever the ball' cock valveitself functions and to maketh'eoperation of such means completely effective to prevent any residual noise or siphoning.

It is also an object' of the present invention to provide a combination ofthe ball cock valveof thecharacterdescribed with a float connection which is more directly and Apositively responsive to the changing water level in a ush vtank to thereby make the action-of the balll cock'- and its anti-Siphon and anti-noise mechanism more accurate and positive in operation.

Itis another object of the present invention to provide a ball cock valve of the character described Which is of relatively simple construction, and which is made of a minimum number of parts and therefore strong and durable and least likely to get out of order, and which is simple-andeasy to install and easy and convenient to-operate.

The foregoingand other advantages and superiorities ofthe ball cock valve and float of the present invention will become more readily apparent to those skilled in the art from the embodiment thereof shown in the accompanying drawing and from the description following. It is to be understood, however, that such embodiment is shown by Way of illustration only, tc make thefprinciples and practice of the inventionfmore readily comprehensible, and Without any intent of limiting the invention to the specific details therein shown.

Fig.'8 isa section taken on line 8 8 of Fig. 1.

Generally stated, the invention consists of a pair of integrally formed intercommunicating cylindrical Valve housings, one of which seats the water valve and the' other an air valve, and a pivoted .leverf arm which is raised and lowered by the water level in the tank in conventional manner and which is connected to the two valves in a mannei` to simultaneously open either of l lar reference to the embodiment thereof illustrated in the accompanying drawings, such valve comprises a dual, integrally formed, preferably integrally cast metal housing, generally designated as I9, and consisting of a pair of valve cylinders, II and I2, preferably coextensive in height, separated by a common wall, I3.

One of the cylinders II, for housing the water admitting valve has an upper open ended, cylindrical bore section I4, and a lower, enlarged bore section I5. The bottom of the cylinder II is substantially completely open and is threaded, as at I6, to receive a plug coupling I1, having the longitudinal passageway I8, therethrough and a threaded intermediate section I9, adapted to engage in the threads I1, an enlarged lower section 25, adapted to overlie the bottom edges of the cylinder II, and a reduced tubular upper or nipple section 2|, extending into the cylinder section I and preferably formed with beveled outer edges 22. The portion of the coupling passageway I3 within the enlarged bottom section 23 thereof may be enlarged and threaded, as at 23, to receive the threaded end of a leader pipe 24, connecting it to the water system.

The cylinder I2 is formed of uniform bore throughout, is open at the top and is preferably provided with a bottom wall 25. The cylinder I2 communicates with the cylinder II through the opening 21, formed at the bottom of the separating wall I3. The bottom wall 25 of the cylinder I2 is provided with a tapped opening 28, in which may be threaded the outlet pipe 29, for the water entering the cylinder I2 from the cylinder I I through the opening 21.

A portion of the wall of the cylinder I2, from about a distance 1/4 of its height from its top to about 1/2 of its height may be pushed out, with its bottom edge severed from the cylinder wall, to form a tapering coping 35, leaving an opening 3|, connecting the interior of the cylinder I2 with the exterior; the lower edge of the coping 39 being preferably supported against the lower wall portion of the cylinder I2 by connecting webs 32.

Arranged within the cylinder II, and fitting snugly therewithin, is a water valve piston 35. The piston 35 is preferably formed with a central annular groove 35, forming a seat for a ring washer 31. The lower end of the piston 35 may be reduced in thickness and threaded to receive a threaded coupling 38, having an inwardly directed downwardly tapering flange 39, at its bottom forming` shoulders adapted to hold a Washer 49, against the bottom end of the piston 35 and forming a downwardly flaring opening below thel washer 49 in position to overlie the beveled end of the nipple 2|, with the washer in position to set on the water admitting opening thereof.

The cylinder I2 may have arranged and snugly fitted therewithin an inverted cup-shaped cylindrical piston 42, having the top wall 43, and the depending side wall 44. The side wall 44 may have a plurality of milled-out openings 45, in its. upper portion, preferably adjacent the top wall, 43, which are adapted to be moved in and out of register with the opening 3| in the valve cylinder I2 for admitting air into it and shutting out air therefrom.

The cylinder II may have cast integrally therewith and preferably on the side opposed to the wall I3 a preferably forked substantially L-shaped bracket 41, extending above the cylinders II and I2. The bracket arm 41 may have pivoted thereon, intermediate its ends, a lever arm 49, as by a pivot pin or rivet 50, which may be threaded, passing through the arms of the forked bracket 41 and through the lever 49 through suitable apertures formed in them.

'I'he lever 49 may engage within an ear 52, formed on the top of the piston 35 and may have its end pivotally connected within the forked upper end of a link 53, as by means of the pin 54; the lower end of such link being pivotally secured, as by pin 55, between the spaced upright lugs 56 formed on the top of the wall 43. An arcuate boss 51 may be formed on the top of the piston 35, within the ear 52, to form a close t for the lever 49 within such ear and on which the lever 49 may bear to lower the piston 35, without too much play.

The other end of the lever 49 may be provided with a vertical, threaded opening 58, therethrough within which may be adjustably arranged a threaded rod 59, vertically set into a float 50; the rod 59 preferably formed with a slotted end 9| to enable its ready and convenient adjustment by means of a screw driver for adjusting the desired water level in a iush tank.

If desired, the lever arm 49 may be provided with a longitudinal boss, 62, within which may be formed a longitudinal, threaded opening, 63, to receive the end of the rod of a conventionally arranged float, in a manner readily understood and not thought necessary to be specifically illustrated or described.

A relatively small threaded outlet opening, 55, may be provided in the wall of the enlarged bore section I5 of the cylinder II to receive an outlet pipe for the overflow of excess water that may be admitted thereinto.

Having thus described the construction of the ball cock valve of the present invention, its operation will now be clear to anyone skilled in the art. It will be readily understood that the water piston 35 and the air piston 42 may be so constructed as to length or height and so arranged Within their respective cylinders and so linked to the lever arm 49, that when the float 6I) is lowered by the receding water level in the flush tank, the end of the lever 49 engaging the piston 35 and the piston 42 will rise. This will simultaneously raise the piston 35 from the nipple 2|, to open the water valve for admitting the water back into the ilush tank, and simultaneously raise the piston 42 to move its openings 45 out of register with the opening 3| into the cylinder I2 to shut out any incoming air and prevent outflow of water therethrough. When the water level in the flush tank is then built up to raise the iloat 59 and its associated end of the lever arm 49, the opposed end of the lever arm will be depressed, to lower the piston 35 into valve closing position and simultaneously and directly lower the piston 42 to bring its openings 45 in register with the opening 3| in the cylinder I2, to admit air into the system to thereby prevent back suction as Well as the hissing noise that is associated with it.

This completes the description of the ball cock valve of the present invention and the manner in which it operates. It will be readily apparent that such ball cock valve is highly leffective and efficient for its purpose of eliminating back suction as well as the associated noise because the air admitting part of the valve is directly and positively operated in the same manner as the water admitting part thereof and by the same force and means, so that the two are actuated simultaneously and function simultaneously but independently of the action of the other.

It will also be apparent that the ball cock valve of the presentinvention is of highly simplied construction involving but a few simple and sturdy movable parts that are not likely to go out of order. It will likewise be apparent that the ball cock valve of the present invention does not require flush tanks as Wide as the conventional ball cock valve installations do, by reason of the arrangement of the iioat with respect to the valve operating lever.

It will be further apparent that numerous variations and modifications may be made in the ball cock valve of the present invention, in accordance with the principles of the invention hereinabove set forth and without the use of any inventive ingenuity. I desire, therefore, to be protected for any and all such variations and modications that may be made within the spirit of the present invention and the scope of the claims hereto appended.
